Fuel E85 (85% Ethanol) - Chevrolet Malibu 2010 Owner's Manual

Fuel E85 (85% Ethanol)

The 8th digit of the Vehicle Identification Number (VIN)
shows the code letter or number that identifies the
vehicle's engine. The VIN is at the top left of the
instrument panel. See Vehicle Identification Number
(VIN) on page 6-102.
If the vehicle has the 2.4L L4 engine (VIN Code 0)
or the 3.5L V6 engine (VIN Code K), you can use
either unleaded gasoline or ethanol fuel containing up
to 85% ethanol (E85). See Fuel on page 6-5. In all other
engines, use only the unleaded gasoline described
under Gasoline Octane on page 6-6.
Only vehicles that have the 2.4L L4 engine (VIN Code 0)
or the 3.5L V6 engine (VIN Code K) can use 85% ethanol
fuel (E85). We encourage the use of E85 in vehicles
that are designed to use it. The ethanol in E85 is a
"renewable" fuel, meaning it is made from renewable
sources such as corn and other crops.

Many service stations will not have an 85% ethanol fuel
(E85) pump available. The U.S. Department of Energy
has an alternative fuels website (www.eere.energy.gov/
afdc/infrastructure/locator.html) that can help you find
E85 fuel. Those stations that do have E85 should have a
label indicating ethanol content. Do not use the fuel if the
ethanol content is greater than 85%.
At a minimum, E85 should meet ASTM Specification
D 5798. By definition, this means that fuel labeled E85
will have an ethanol content between 70% and 85%.
Filling the fuel tank with fuel mixtures that do not meet
ASTM specifications can affect driveability and could
cause the malfunction indicator lamp to come on.
To ensure quick starts in the wintertime, the E85 fuel
must be formulated properly for your climate according
to ASTM specification D 5798. If you have trouble
starting on E85, it could be because the E85 fuel is not
properly formulated for your climate. If this happens,
switching to gasoline or adding gasoline to the fuel tank
can improve starting. For good starting and heater
efficiency below 32°F (0°C), the fuel mix in the fuel tank
should contain no more than 70% ethanol. It is best
not to alternate repeatedly between gasoline and E85.
